General Safety Rules:
1. Read all directions for an experiment and follow the directions exactly as they are
written. If in doubt, ask the teacher.
2. Never perform experiments that are not authorized by your teacher. Always obtain
permission before experimenting on your own.
3. Never handle any equipment unless you have specific permission.
4. Take care not to spill any materials in the lab. If a spill occurs, ash your teacher
immediately about the proper clean-up procedure.
5. Dispose of all material according to the teacher’s instructions. Never empty materials into
the sink or trash can.
6. Never eat in the laboratory. Wash your hands before and after each experiment.
7. Never horse play or run in the laboratory. This will earn you a zero and dismissal from
the lab.
